Did you know that you can do a find for something like H2O and replace it with H2O, m3 with m3, and kg-1 with kg1?
Word’s Find and Replace to the rescue… In this example, I’ll use H2O but the same technique applies for anything similar.
- Change one of the incorrect instances of H2SO4 to the correct formatting (H2SO4).
- Copy the correct format (H2SO4) to the clipboard (select all the text and then press Ctrl+C).
- Open Word’s Find and Replace (Ctrl+H).
- In the Find what field, type H2O (the incorrect format).
- In the Replace with field, type ^c (that’s a Shift+6 for the caret [^] character and a lower case ‘c‘ — the ‘c’ MUST be lower case).
- Click Replace All.
